IMPROVEM ENT lN SULKY-PLOWS.

Specification forming part of Letters Patent No. 207,598, datedSeptember 3, 1878; application filed July 19, 1378.

To all whom it may concern:

Be it known that I, J AY Bosrwrcx Frsnnn, of Davenport, inthe county ofScott and State of Iowa, have invented certain new and usefulImprovements in Sulky-Plows; and I do hereby declare that the followingis afull, clear, and exact description thereof, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

My invention relates to sulky-plows which are supported on wheels andprovided with a seat for the operator.

The invention consists in a new form of axle, by means of which thesulky-frame is leveled, and the land-side wheel passes over unevenground without affecting the plow in the furrow.

The invention further consists in certain new combination of devices,all as hereinafter more fully set forth.

In the accompanying drawings, Figure l is a rear view of my improvedsulky-plow axle and adjusting devices, with the wheels, plow, tongue,rack, and rear end of the reach, havmg a guide caster-wheel, removed,all of which are in my drawings of Letters Patent May 21, 1878, No.203,903, to which I will refer for the said parts removed. Fig. 2 is adetail view of the lower portion of the adjustable device which operatesthe plow, having the handles removed. Fig. 3 is a detail view of an en.larged cross-section of the furrow-side end of the axle andcrank-spindle, which is secured therein, showing how the spindle isadjusted and operated. Fig. 4 is a detailed view of an enlarged end ofthe adjusting semicircular rim, and cross-section of the crank-spindle,showing the manner of fastening them together. Fig. 5 is a detail planor top view of the landside end of the axle and spindle, hinged to theaxle in a tapering slot. Fig. 6 is a perspective detail view of theadjustable device which operates the plow. Fig. 7 is a perspectivedetail view of the spring-lever, secured to the .lock and operativelevers.

Referring to parts by letters, A represents the tubular axle, which hasa tapering slot in l the top of the land-side end, (see Fig. 5,) for thepurpose of hingin g the tapering spindle or axle B at a with the pin a,having its lower bearing in the tapering slot a The spindle B has itsbearing on the wheel removed, and moves up and down in the slot 1)formed by the staple c, which is fastened to the upper edges of thetapering slot a near the end of the tubular axle A, as the wheel passesover uneven ground in cutting a ribbon or furrow with a plow across afield.

The coil-spring O embraces the staple c, and has its upper bearinginthetop of the said staple, and it is pressed down under the pin b wheneverit is necessary to stiffen the coil-sprin g 0. The lower end of thecoil-sprin g G has its bearing against the spindle B, so as to pret enta too free motion of the wheel in a vertical and lateral direction, andyet to permit of its movement in this direction when passing over unevenground or obstacles without moving the plow from its true workingposition. As the wheel rises with the spindle B the bottom moves outwardand the top inward, producing a lateral movement with the upward.

The arc-shaped reach A is fastened to the tubular axle A near thecenter, at right angle, having the rear portion, resting on a guidewheeland lever-rack, removed. D is the crank spindle or axle, having itsbearing on the old furrow-wheel, which is removed, and the end, which isprovided with lengthwise grooves d and annular grooves d, having itsbearing in the furrow-side end of the tubular axle A. The crank-axle Dis secured and ad justed therein by means of the screw 0?. (See Fig. 3.)

E is the semicircular rim or bar, which is bolted to the elbow of leverF at the center,

and having one end, 0, clasping the tubular axle A between two pins, andits end cut away so as to permit the movement of the spindle B up anddown in the slot a (see Figs. 1 and 5) when the plow is in the furrow.

The grooved end of the spindle 1) passes through the feathered end 0 ofthe rim E, as seen in Fig. 1, and is secured therein by the screw orbolt 0 (See Fig. 4.)

The lockage of the end 0 with the bolt c takes the crank-spindle D alongwith the rim E in its up-and-down movement produced by thelever F inraising and lowering the plow, which levels the sulky-frame.

The slotted plate I has journal or hinge bearing ends. The bifurcatedhandles J and bent lever f 2 are fastened to the plate J, which ishinged to the upper end of the slotted plate I. The spring-bow j isfastened to the bifurcated arms f, which has its collar-bearin g neckhinged or pivoted to the lever F. (See Fig. 1.) Its lower ends arejournal-bearing.

The bent lever f locks the handles J by pressing the said bent leverinto the bow j with the handles J. The forward bifurcated end of thelever F, which has its bearing on the front end of the plow-beam whenraising the plow, is removed, but seen in my patent referred to issuedMay 21, 1878, No. 203,903.

The bent yoke H has journal ends h slot 71., and journal-bearing neck,by which it is pivoted to the slotted plate I with the journalpin hwhich moves up and down in the slot i.

The cam K is pivoted above the pin 70 (see Fig. 1) to the slotted plateI, to prevent the pin h from moving up and down too freely in the slot1', but permitting of it, when the handles J move the plow-beamlaterally, taking the cam K along with them, (see Fig. 2,) so that thepin h will rise in the slot '5 to lengthen out the operative device, soas not to raise the plow from its true working position in the centrallateral movement.

L are the knee-pans, which are fastened near the lower end of theslotted plate I. They extend rearward and turn back upon the slottedplate I, so that they will bear on the top of the plow-beam and limitthe forward movement of the plow by taking the sulky along with thedraft of the plow. The lower end of the slotted plate I is hinged orpivoted to the plow-beam.

M is a bifurcated lock-lever, which is hinged or pivoted loosely to thelever F by its neck 'm above the neck f. The arms m of the bifurcatedlock-lever M extend downward under the semicircular rim E, and then upover the bifurcated arm f, and are clinched at the ends m ,in order tosecure a firmbearing of the arms f on the rim E, and lock them thereon,when desired, by means of a spring-lever, N. The said spring-lever hasits lower bent end, 01., fastened to the neck m of the lock-lever M, andhaving the upper end resting in a groove, n, of the lever F, forming asemicircle, n thereat, and at the end a lock-slot, n Pressing the saidlock-slot end-against the lever F raises and locks the lock-lever M,when required by the operator, and loosened whenever the land-side wheelis passing over a knoll or running on a corn-hill row, or whenever thesulky-fra-me is liable to tip or rock, in order that the plow-beam willremain vertical. The lateral and vertical movements of the sulkyframe bymeans of hingin g the bifurcated arms f on the lever F, and the spindleB bearing against the coil-spring 0, both reducing the draft of the plowone-quarter.

I may desire to use any other means of securing a lateral hinge or pivotof the plowbeam to the axle or sulky-frame; also any kind of springwhich will regulate the up, down, or lateral movement of the land-sidewheel in its passage over uneven ground without effecting the trueposition of the plow in the furrow.

M is a seat, secured to the reach A. For smooth ground, Fig. 6 is asubstitute for Fig. 2. O is the yoke, having a swivel-bearing neck, 0,projecting backward, to permit of the rising of the plow without liftingthe sulkyframe when striking obstacles, in order to free itself, and thejournal ends work in the arms f. P is the bifurcated arm, havingjournalbearing ends and swivel-journal neck 1) and knee-pans 19 whichbear on the plow-beam and limit its forward motion. The journalneck 19is swiveled to the swivel-bearing neck 0 by the nut p, which forces anup, down, or circular motion of the plow. The lower ends of thebifurcated arms P are hinged or pivoted to the plow-beam.

It will be seen that the plow is raised or lowered and the sulky-frameleveled at the same time by the operation of the lever F,

first raising the point so the beam will bear against the bifurcated endof lever F, (seen in my sulky-plow, May 21, 1878, No. 203,903,) and thenraising the entire plow above the ground. The handles J are managed bythe driver on the seat, and the lever f 2 looks them in the bow j, whendesired. (See my sulkyplow No. 203,903.)
